ETS Corvette C8 5.0" High Flow Catalytic Converters

ETS Corvette C8 5.0" High-Flow Catalytic Converters Maximum flow. Serious horsepower capability. Without the compromises of going catless. The ETS 5" High-Flow Catted Downpipes are designed for high-horsepower C8 Corvette builds that need exceptional exhaust flow without giving up the benefits of a catalytic converter. Instead of using the smaller 4" high-flow cats commonly found in performance exhaust systems, ETS steps up to massive GESi G-Sport Gen2 UHO+ 5" high-flow catalytic converters. The larger diameter provides substantially more catalyst and potential flow area, helping reduce restriction as power levels climb. Why 5" Matters A 5" diameter core provides approximately 56% more cross-sectional area than a 4" core—19.63 in² versus 12.57 in². That additional area gives the exhaust significantly more room to flow through the catalyst, making our 5" HFC setup an excellent choice for 1,000+ WHP applications where a smaller catalytic converter can become a restriction. Big Power Without the Catless Smell Going catless may eliminate a restriction, but it also comes with one of the biggest complaints on a street-driven performance car: raw exhaust and fuel smell. Our 5" high-flow cats are designed to provide the flow capacity needed for serious horsepower while significantly reducing the unpleasant exhaust odor associated with a catless setup. You get a system capable of supporting 1,000+ WHP without sacrificing the street-friendly benefits of a properly catted exhaust. Complete Direct-Replacement Package ETS designed the system as a direct replacement for the factory catalytic converter assemblies. Everything needed for installation is included, eliminating the need to source additional hardware or fabricate components.
